construction engineering; sports-entertainment facilities. SUBSTANCE: framework has flat foundation- mounted girt-and-stanchion assemblies incorporating stand frames including stanchions, inclined upper girt rails and horizontal girts, L-shaped roof frames with stanchions over external perimeter of stand frames, and girt rails carrying roof components above stand frames, as well as frame-to-frame braces. L-shaped frame stanchions are provided with supporting members, engageable with upper part of stand frame and connecting members engageable with extreme stanchion of stand frame. Tension bars are installed between post feet of stand frame, inclined girth rail, and L-shaped frame stanchion. Inclined girth rail has stepped upper fillet. L-shaped frame stanchion is composite structure made of vertical and inclined fillets radiating from its foot with strut placed between their upper parts; vertical and inclined fillets joined together by diagonal web in section above supporting member. L-shaped girth rail of frame has extreme mount on vertical fillet or its stanchion and intermediate one in hanger fastening joint connecting the latter to upper part of L-shaped stanchion of frame. Braces between L-shaped frames are mounted on strut plane at vertical fillets of stanchions above supporting member and in plane crossing points where axes of supporting members and vertical fillets of L-shaped frames intersect. EFFECT: reduced metal input and labor consumption; improved appearance; increase reliability. 4 dwg
